A new experimental model of dominant was developed by the author, the
so called a ''polarization'' hunger dominant created by application of
weak direct current to the lateral hypothalamus in combination with a
sound stimulus, There was an increase in the delta component of the e
lectrical activity of the left parietal cortex (the dominant focus) wh
ile the EEG spectral power of the other cortical areas, lateral and ve
ntrolateral hypothalamus decreased in the slow-wave ranges.
